WebMar 20, 2024 · Brittle fracture of material refers to the type of failure mechanism where material shows little or no deformation and it’s a sudden failure without any warning. Breaking of rock, glass, cast iron is an example of brittle fractures as they break without any deformation. A ductile fracture means fracture of material with large plastic ... WebSep 7, 2024 · Below a critical temperature, termed the ductile-to-brittle transition temperature (DBTT), the plasticity of BCC metals displays an abrupt transition from ductile deformation to cleavage brittle fracture (1–9), limiting the temperature window for the utilization of these metals (1–9). Therefore, a thorough understanding of the mechanism ... caitlin holly jones
